Abstract

A damper for an upright piano is provided for improving sound stopping capabilities and consequently improving sequential touching capabilities without adversely affecting a key touch feeling. The damper lever for an upright piano is pressed against a vibrating string to stop the vibration in response to a released key, in order to stop sound which has been generated from the vibrating string. The damper lever comprises a molding molded by a continuous fiber method and made of a thermoplastic resin containing long fibers for reinforcement.
